Résumé and Publications

Hi and Welcome to my web page. I'm a research scientist at UCLA where I'm using Synthetic Aperture Radar Interferometry to study a variety of processes that affect the surface of the earth. I hope that you will take a moment to look around the page and let me know if you are interested in any of the topics.

Surface Processes

Hydrology studies using GIS and SAR Interferometry:

Changes in Floodplain Storage Extrapolation of SIR-C observations in a GIS of the central Amazon floodplain yields an estimate of floodplain storage. This paper is in review.

Water Level Change over 44-days! Volumetric measure of storage change derived by combining radar altimetry with SAR interferometry. Published in the July 15, 2001 Geophysical Research Letters.

We find that the volumetric change in storage in the Balbina Reservoir was about 280 million cubic meters over a 44-day time span. Click on the link for a better view of the cover of GRL.

Water Level Change over one-day! "Displacement" of the water surface measured with SAR interferometry. Published in the March 9, 2000 Nature.

Glacier Studies with SAR Interferometry:

Ice velocity and Anomalous Topography Using interferometric SAR, we are able to measure changes related to the subglacial eruption and subsequent catastrophic flood.

Digital Elevation Models from SAR Interferometry:

Topography from Satellites The European Space Agency has several radar satellites, this image was created from data collected by ERS 1 and 2.

I will update this section with a very large (15 frame) DEM that I am making for a portion of the Argentinian Andes. This is work that I am doing with my colleague, Dr. Benjamin Brooks at SOEST in Hawaii.

Earthquake Studies with SAR Interferometry:

Lithospheric Structure of Tibet and the Middle East

Satellite Magnetics
